Induction melting rauv soj ntsuam txoj kev

Tom qab lub induction melting rauv yog ntsia, yuav tsum muaj kev soj ntsuam xyuas ntawm cov khoom siv fais fab mov system.

Txiav tawm lub hwj chim mov ntawm lub induction melting rauv, open the power cabinet door and carefully tighten the bolts; check and tighten the crimping parts: the bolt contacts are loose; poor contact should be repaired in time; replacement, do not use reluctantly, so as to avoid greater accidents. In particular, always check whether the contact of the main contactor is oxidized; if it is loose, remove the problem in time to prolong the service life of the induction melting furnace and ensure the safe and reliable operation of the induction melting furnace.

Ntxuav cov plua plav hauv lub txee fais fab, tshwj xeeb tshaj yog sab nraud ntawm silicon tswj cov khoom tuag, so nws nrog cawv. Plua plav yuav txo cov rwb thaiv tsev ntawm cov khoom siv hluav taws xob, thiab qhov chaw tawm ntawm cov khoom feem ntau tshwm sim thaum muaj plua plav ntau thiab cov av noo siab.

Tshawb xyuas seb cov xaim ntawm lub thauj khoom puas zoo li qub thiab seb qhov rwb thaiv tsev puas txhim khu kev qha. Xyuas seb SCR tswj cov hlau lead puas yog nyob rau hauv kev sib cuag nrog lub anode ntawm cov khoom: Siv lub multimeter R × K los ntsuas qhov tsis kam ntawm cathode thiab anode ntawm SCR los txiav txim qhov kev txiav txim. Lub rectifier thyristor yuav tsum yog ob peb puas KΩ, thiab lub inverter thyristor yuav tsum yog kaum ntawm KΩ. Tom qab ntawd siv cov ntaub ntawv R × 1 los xyuas seb puas muaj qhov luv luv lossis qhib Circuit Court ntawm cov tswj electrode thiab cathode ntawm thyristor. Yog tias muaj teeb meem, teeb meem nws.

Cov hlau yas; cov kav dej yas yuav tsum tsis txhob sib tsoo nrog cov khoom siv hluav taws xob cua sov. Tshawb xyuas seb qhov kev tiv thaiv-capacitance ceg ntawm lub inverter thyristor ntawm lub induction melting rauv yog xoob los yog tsis zoo tiv tauj, cov tooj liab busbar; seb lub cable puas zoo thiab seb lub capacitor bracket insulator puas zoo.

Xyuas seb lub hwj huam mov Circuit Court ntawm lub induction melting rauv puas zoo txuas thiab seb lub cable puas tau pw zoo. Peb-theem cov kab nkag yuav tsum tau txuas nrog raws li theem ib ntus cim ntawm txoj haujlwm ntawm cov kab nkag. Xyuas cov nyees khawm ntawm lub vaj huam sib luag tswj ntawm qhov nruab nrab zaus fais fab mov. Lub hwj chim hloov potentiometer thaum lub qhov cub induction melting yog nyob rau hauv standby hom yuav tsum nyob rau ntawm xoom txoj hauj lwm.
